让我重新提出问题
我有一个ASP.Net页面，其中包含数据字段和2个按钮，用于检查公司是否存在（此工作正常）。
按钮2需要插入值
[ID]
,[BEDRIJF]
,[FUNCTIE]
,[TITEL]
,[VOORNAAM]
,[VOORLETTERS]
,[TUSSENVOEGSEL]
,[ACHTERNAAM]
,[SEXE]
,[ADRES]
,[PCPLAATS]
,[LAND]
,[EMAIL]
,[BRANCHE]
,[TELEFOON]
,[MOBIEL]
,[DATUM_BRIEF]
,[VEBAN]
,[PAYOFF]
从页面上的文本框单选按钮和下拉列表中。

但是这个dosnt工作，它会执行插入，也不会将标签16文本更改为数据保存或数据未保存。
有人可以指出按钮无效的原因。
一些见解SQL和SQL连接不是我正常的编程区域，正常构建基本的Windows应用程序，具有简单的布局和同事要求的简单功能。
aspx.cs文件中的按钮单击功能
protected void Button2_Click(object sender, EventArgs e)
{
string connString = ConfigurationManager.ConnectionStrings["FUP-DataConnectionString"].ConnectionString;
SqlConnection conn = null;
try
{
SqlCommand cmd = new SqlCommand("sp_insert", con);
cmd.CommandType = CommandType.Text;
cmd.Parameters.AddWithValue("@BEDRIJF", TextBox17.Text);
cmd.Parameters.AddWithValue("@VOORNAAM", TextBox6.Text);
cmd.Parameters.AddWithValue("@ACHTERNAAM", TextBox8.Text);
con.Open();
int i = cmd.ExecuteNonQuery();
if (i != 1)
{
Label16.Text = ("Data Saved");
Response.AppendHeader("Refresh", "5;url=Default2.aspx");
}
else
{
Label16.Text = ("Data Not Saved");
Response.AppendHeader("Refresh", "5;url=Default2.aspx");
}
}
catch (Exception ex)
{
//log error
//display friendly error to user
}
finally
{
if (conn != null)
{
//cleanup connection i.e close
}
}
}
}
答案 0 :(得分：1)
尝试：
cmd.CommandType = CommandType.Text;
cmd.CommandText = "INSERT INTO Data Values (@BEDRIJF,@VOORNAAM)";
cmd.Parameters.AddWithValue("@BEDRIJF", BEDRIJF);
cmd.Parameters.AddWithValue("@VOORNAAM", VOORNAAM);
不要在引号中包含您的参数。
Why I'm getting CS1012: "Too many characters in character literal" and CS0019?
答案 1 :(得分：0)
我认为你正在使用参数智能插入
string BEDRIJF = TextBox17.Text;
string VOORNAAM = TextBox6.Text; // Scrub user data
string VOORLETTERS = TextBox5.Text;
string Tussenvoegsel = TextBox7.Text;
string connString = ConfigurationManager.ConnectionStrings["FUP-DataConnectionString"].ConnectionString;
SqlConnection conn = null;
try
{
conn = new SqlConnection(connString);
conn.Open();
using (SqlCommand cmd = new SqlCommand())
{
cmd.CommandType = CommandType.Text;
cmd.CommandText = "INSERT INTO Data Values ('@BEDRIJF','@VOORNAAM')";
cmd.Parameters.AddWithValue("@BEDRIJF", BEDRIJF);
cmd.Parameters.AddWithValue("@VOORNAAM", VOORNAAM);
int rowsAffected = cmd.ExecuteNonQuery();
if (rowsAffected == 1)
{
//Success notification
}
else
{
//Error notification
}
}
}
catch (Exception ex)
{
//log error
//display friendly error to user
}
finally
{
if (conn != null)
{
//cleanup connection i.e close
}
在错误的地方看到这部分
cmd.CommandText = "INSERT INTO Data Values ('@BEDRIJF','@VOORNAAM')";
cmd.Parameters.AddWithValue("@BEDRIJF", BEDRIJF);
cmd.Parameters.AddWithValue("@VOORNAAM", VOORNAAM);
